Writing video vs conforming to mpeg 2 when rendering?

Just when it seems I understand what the heck I am doing, another issue crops up. I have been happily editing along for the last few weeks in the XDCAM HD timeline and rendering when needed ( a lot ) but the renders seem somewhat fast so things are good. All of a sudden when I render, it is conforming and not writing to video. Which takes much longer. Checked all my settings and they are the same as the last few weeks. Where have I gone wrong?
Best,
Tom

It sounds like the GOP structure is needing to be rebuilt...(that's what "conforming" is) just like HDV has GOP, so does every format from Sony contain this structure... except HDCAM, DVCAM, and DV. Only fix is not to edit with GOP structured MPEG based media. You can transcode it to ProRes (an all i frame format) and get around this... It's what I do when receiving HDV source material.
Might try rendering to ProRes to speed this up... That setting is found in the sequence's render setting's tab when you select that sequence and type cmd+zero.

Is there a final video size limit or restriction when rendering a composition?

Im a self thought After effect user, so I might not know the exact terms that I need to use for my question. I need to create a video thats is in its final size 1080x3840 px. This is being used in a two screen setup and being played by a single player that splits this on video into the two screens without having to create two separate videos. I can create the composition size to the pixels needed but when I render the video it automatically refers the video to 1080x1920 px which is the size of only one screen. When this render happens the top and bottom of the video get cut off. I have create the final video to 3840x1080 px but this is not what works for the set up. Does After Effects have a height limit when it comes to the final output of the composition? If it does, can it be unlocked so i can create the final 1080x3840 px? Do I need to use an other program to accomplish this, anything would help. The codec I'm using is H.264 at a 10 Mbps. Thank you

Well what i got from them is that they need the the file to be on H.264 codec at 10-15 Mbps at the size of 3840x1080 px. It would be played by one player that uses the H.264 codec. All i need is to be able to do is to output the final video to the size they are asking since everything else works fine. I want to know if i could make the final video size in After Effects or if I have to switch the layout to 1080x3480 px since that has no restrains and then bring it into another program. I have done multiple video files for them and the work fine but they are not to the size they need since every time I render the composition it crops it from 3840x1080 px to 1920x1080 px leaving the the top and bottom of the video out completely.

"Conforming HDV" instead of "Writing Video" while rendering anything

I am having a serious issue with FCP. I am getting the "Conforming HDV" dialog instead of "Writing Video" while rendering anything
Short Project shot @ 720p 30 with a JVC GY-HD100U
1) This gradually started happening more and more.
2) Whenever I try to render anything, even a small crossfade, FCP shows the "Conforming HDV" dialog and proceeds to trash my video. Pieces of the video are repeated or frames are dropped and shots become jerky.
Undo fixes the issue. Replacing the video with the original fixes the issue. But I connot RENDER ANYTHING!
What would you all suggest?

Welcome to HDV. I've never had much better luck than this. The way the GOP structure of the mpeg-2 HDV stream works, the I-frames in your media almost never match up with the default GOP structure of the sequence, and you must wait for it to conform everytime you even think about touching it. Changing the render settings might help. If you are still runnning FCP 4.5, you will be plagued with scrambled render files - even if you can get it to show the correct rendered material in the timeline, if you export or encode or output to tape, you'll wind up with different (wrong) renders in the resulting files.
You might consider batch exporting all your media to Apple Intermediate Codec (AIC), an all I-frame codec that helps to get around some of the GOP structure issues that make HDV so impossible to work with. Also, more RAM, or a better video card will take some of the load off of the processor as it tries valiantly to decode the HDV stream. Upgrading FCP to the latest version will also help with some of the render-scrambling etc.
Hope this helps -

Writing Video when laying back to tape, despite timeline been rendered...

Hi
I have a 97 minute timeline fully rendered @ Uncompressed 10bit 24sf video.
I'm trying to play out to a HDCAM SR deck via SDI output on a KONA 3 card through edit to tape. The timeline is fully rendered and plays back real time when I hit space bar and if I just want to crash record to the deck. However when I use edit to tape and try to do an assemble edit a message bar pops up saying writing video and gives me a write time of 7 hours. Does anyone know why this might be...?
My sequence settings match all my set up and deck control settings. I've double and triple checked the video format the KONA is outputting using the AJA utility... any ideas?
Thanks in advance.
Jonny

Check the settings playback settings in the Timeline window to make sure they are all set to be high quality... sounds like the playback/render quality doesn't match the recording quality so when you ask to edit to tape, it is attempting a total re render.

*** Turning off "conforming HDV video" when renderring?

Based on a previous post, and in the interest of speeding up my print to video time, in the sequence menu in the nav bar in FCP I changed "something" that means that whenever I render my HDV video now, it says "conforming HDV video". This is now slowing down my editing time because I don't want to conform the video every time I render a clip. Any idea how to turn this "off" for the time being? Is this even possible?

When you select Sequence > Render All, that will Conform everything that gets rendered. If, instead, you first click to highlight the clips in the Timeline you want to render, and then select Sequence > Render Selection, FCP will only render, and will not conform.
However, this will mean that when you Print to Video, Final Cut will have to conform the entire sequence, which will take a very long time.
It's like the old Fram commercials - "you can pay me now, or you can pay me later." At some point, Final Cut will have to conform.

"Writing Video" though Sequence already rendered

Hello. This happens occassionally though not sure why... I'm editing to tape, an assemble edit to a digi...something that we've done many times...the sequence is fully rendered..but when I edit to tape, FCP starts "writing video" which currently is taking over an hour...the other downside is that EVERY time I edit to tape when this happens, I have to go through the "writing video" process...why is this happening and how do I get it to stop? Usually if the sequence is rendered, I don't have to write video, or it's very quick so I don't mind, but I can never tell when or why this happens. THanks!

Sorry, I was thinking "writing audio" when you were saying "writing video"
I've had this happen occasionally as well and not sure why, but, a way around it is to export your sequence to a self contained QT movie using current settings and reimport that file for PTT.
Takes some drive space, but I find it's also a more stable method for getting to tape than running a complex timeline using PPT. And it also serves as file copy of my final sequence.

Writing video files in an App - Crashes when used repeatedly.

When we are writing video using the UIImagePicker routine the App can crash after repeated recordings. Is this problem related to filling up the RAM faster than the video can be written to Flash? If so, what work around might there be? Or avoiding this by registering Free Ram Space and delaying users activity?

Hello
Sometimes the Adobe Viewer, or a custom Viewer, appears to crash. However, the iOS is in fact shutting it down because of a low memory state. You can confirm whether you have this issue by syncing an affected iPad to a Mac. Then retrieve the logs to see if there are LowMemory-[time stamp].log files. Here is where such log files, as well as crash log files, is found:
Users/[user name]/Library/Logs/CrashReporter/MobileDevice/[device name]
Look for a LowMemory log file with a time stamp that corresponds to the application's exit. Open it in a text editor and look for a line like the following:
viewer <42d0b24207f7d625b2fefef7549afce3> 33490 (jettisoned) (active)
The numbers can vary. However, if the line indicates that the "viewer" process was "jettisoned" while "active," the OS closed the process because of a low memory state. The most likely reason for this is that your viewer is reading into memory images that are larger than 1024 x 1024. Apple recommends against applications loading any image larger than this size as it contributes to a low memory state on the device. It can result in what appear to be application crashes. Review your folio source files and ensure that no images of greater size are used. If they are, simply resample them, and republish your content.
The low memory state can also be the result of having too many applications running at once. Shut down applications you are not actively using to free up more memory.
How to free up memory on your iPad
1. From the home screen, double-click the Home button to display recently used applications.
2. Tap and hold one of the applications until a red minus appears above it.
3. Tap the red minus for all apps that are not currently needed.
4. Tap anywhere above the list of recently used apps, to return to the home screen.

Changing animation frame rate when rendering in photoshop does not change the length of the video?

I made a walk cycle animation in Photoshop CS6 and want to render it into a quicktime format. I'd like it to be 12 fps, but when I rendered it at 12 fps the video seemed to be missing frames, and the video was 3 seconds long. I have 98 frames to my animation; doing the math, at 12 fps it should be 8 seconds long. Not 3.
I was confused and for curiosity's sake I rendered the video at 6 fps, trying to really slow it down. The video ended up being STILL 3 seconds long and only maybe 20 frames. I was missing literally 70 frames. I'm so upset with this rendering thing, I could chuck my computer at the wall.
Does anybody know of a solution to this?
edit: If it means anything, I've tried rendering it straight from the frame view and the timeline view. Each time I render it I have the timeline frame rate match the rendering frame rate as well.

Photoshop CS6 and CC support two types of animation Frame animations and a Video Timeline
Changing the frame rate should not change the length of a video timeline. It should just change the number of frames that are rendered. To change the length of a video you need to change the length of the video timeline. If you increase the length of the timeline and there is audio I'm quite sure there will be a problem with it, The Video part will most likely be better then the sound. The required number of extra frames can be generated however the video may look like slow motion. If you decrease the length the motion will speed up. The length of a video is normally done be editing video clips which are trimmed and stitched together to get the desired duration. Not normally done by altering the duration of a clip.
The duration a of Frame animation is the sum of the times each frame is displayed. In a frame animation the length of time a frame is displayed can be varied it not a normal motion picture video. To have a smooth frame animation you need a sufficient number of frames that are different from each other to show smooth motion. You can use Photoshop Frame animation tween feature to have Photoshop manufacture frames to help with a smoothing the animation. Once you have a frame animation the length with the motion you want you can have Photoshop convert it to a video timeline and render a normal motion picture video. It will not have audio but you can add audio to it.

HT3775 how can i open the file MPEG-2 Video, AC3 on my mac, when its coming from a sony camcorder?

how can i open the file MPEG-2 Video, AC3 on my mac, when its coming from a sony camcorder?

I think those files are Samsung's proprietary format, so only the Samsung software can open and display them. If they do not make their software for OS X, then you are stuck requiring windows.
I thought the DVR itself lets you save as standard avi as the backup file format?

Video slips when rendered - a 24p problem?

Hi
I use a Panasonic DVX100B to shoot and Final Cut Studio 2 for post. On this video I am working on I make my cuts where I want them, but then if I apply any effect requiring a render, the clips slip by about 2 seconds when rendered. If a certain clip has an effect, but can play without render, then I get the slip when I export as a QT - surprise! Weirder, this only happens with some but not all of my footage.
I think it must have something to do with the 24p Advanced Pulldown Removal. Like the missing frames confuse the render function, which goes to get its info from the wrong place.
When I shoot 24p I can capture it with my settings as straight DV/NTSC or as 24p APR. (Usually I use capture now, as I find the camera often has trouble finding the start frame when I log first).
When I capture DV/NTSC I get no weirdness, but all my duplicate frames are there of course and when I edit into a 24fps timeline the wrong frames are removed. (Some way to make that not happen?)
When I capture APR I sometimes get audio out of synch, and I sometimes get this slipping when rendered problem.
Anyone know what I'm doing wrong? I'd be so grateful to know.

My preset in CS3 is HDV 1080p30. The stills were taken from videotaping photos with my SONY Z5U camcorder. I believe they are 1920x1080p.
So you were using 1920 source in a 1440 preset. You then did frame grabs to create the stills? How did yo do that? You may be exporting to yet a different format.
So, rather than reverse engineering your whole workfflow; it would be easier to examine the actual source being used in the new project. Can you provide the details on the actual assets being used? IN CS4 it is very easy to create a new sequence in the same project with the correct aspect ratio; assuming that is the problem. But we are still shooting in the dark since we dont know the details of your assetts.

IMovie audio issues. Fine in timeline, but when rendering to iTunes or Media Browser, audio from certain portions of movie files are heard in places where it shouldn't be !

iMovie 11 audio issues. Fine in timeline, but when rendering to iTunes or Media Browser, audio from certain portions of movie files are heard in places where it shouldn't be !
I have created a project where I have a montage of photos and video clips edited together with music under. Some audio portions of the video files are being muted in some areas and those portions are being heard in another part of the project. This is not for all video clips only certain ones.
The project plays fine in the timeline, but when I render the project thru iTunes or Media Browser, this is when the project goes corrupt.
I tried detaching the Audio from the video clips and this somewhat worked, but the original problem still exists with certain audio still being heard where it's not supposed to be.

I have a fix - or rather, a workaround.
WARNING: It is lengthy, but still far better than starting a new project from scratch.
I had this same issue and none of my transitions/clips were at custom speeds, nor did I have anything else weird going on. Unfortunately there is nothing you can do within iMovie to fix this, at least there wasn't for me. iMovie is BY FAR the buggiest software I have ever used and if you haven't already spent hours slaving away on a project, you are so much better off using just about anything else to edit your video.
...But let's assume you have already spent many hours working on your project and you don't want to start all over. Well then, you have at least one option.
It's a pain in the neck, but it's infinitely better than restarting your project from scratch.
This will require:
A software called Soundflower (which is free) and some kind of audio editing software (I use Logic, but really any should work).
1.) You're going to need to export your video with the messed up audio. Typically if you're audio is messing up, you're video is at least usually working just fine (at least it always does for me).
2.) You're going to need to open that video in your audio software and import only the audio. If your software doesn't give you this option, then you're going to need to record the audio from your video using the audio software and Soundflower. You can find tutorials on how to do this, but it's honestly pretty straightforward once you start playing around with you Mac's audio I/O settings. Remember to have your computer's volume all the way up when doing this.
3.) Watch/listen to your video and make notes of where the audio errors occur. I HIGHLY RECOMMEND writing down times too, as they will be extremely helpful later.
4.) Now were going to rip some working audio from the iMovie project itself. Go back into your iMovie project and only play back audio while in the edit window for this step. Do NOT play your project back in full screen.
This part is key: if you try to play back your project from the beginning the audio will usually still mess up. So, what you're gonna have to do is go back on your edit window timeline right before these errors occur and play that specific clip back while recording this working audio with Soundflower and your audio software. Essentially we're only recording the parts of the audio where these errors occur, so try to do this in order if you can. Try to leave several seconds of audio in before the error - that way we can use it as reference when we construct our new audio track.
5.) Now in your audio software you should have your original error-filled audio track and the new clips that we just captured. This part can be painstaking if you're not familiar with audio editing softwares, but as you'll learn, it's really not that hard.
You're going to look at your original audio track and compare it to your new working audio clips. You should be able to notice where those new clips are supposed to go by looking at the identical (or close to identical) waveform shapes in your original audio track. The two should correspond with one another. If you don't understand what I mean right now, you will when you start playing around with the audio. This is why marking times is very important.
Take your new clips and split them up if you haven't already, that way you can drag them around and edit them separately from one another. Essentially your going to line these new clips up with original and then replace the original parts with new ones.
We need to get this as precise as possible, so start off by getting them as close as you can with your naked eye, and then use a zoom tool to zoom in as much as possible so that you can get them lined up PERFECTLY, or at least extremely close. In some softwares you can just drag these new clips on top of the old track, but most of the time you will need to actually cut out the old piece and replace it with the new one. In doing this, zoom in and make sure that you are NOT cutting out a bigger space than your new clip will fill - otherwise you will have small gaps in your audio.
VERY IMPORTANT: Also make sure that this new audio track starts at the EXACT SAME time as your original - otherwise your new audio will be out of sync.
I know this part can really suck if you're not used to audio editing, but at this point, there is little other choice.
6.) Once you are done with this, export your newly pieced together audio track.
7.) Now open iMovie and create a NEW project. Re-import the video that you exported earlier that has the messed up audio. This might take a while, so just be patient.
8.) Then right click the clip and select "Detach Audio". This will do just that - allowing you to edit the audio separately from the video. Now delete this audio.
9.) Now, import the new, perfect audio track that we just made and make sure that it starts at the start of the project. Make sure it's in sync and that everything works.
Now just export your new video with the working audio and you should be done. Since we have given iMovie the audio with no editing actually being done in iMovie, it does not have to generate its own audio now and you should have absolutely no errors now - unless there is some that you forgot to take out earlier.
YOU'RE FINALLY DONE!!!
I know this entire process *****, but if you're that far into your project, there is little else that you can do. Now you've learned your lesson:
DON'T USE IMOVIE EVER AGAIN.
I hope this helped!

AV sync problems when rendering Quicktime in PE 8

I have a simple problem when rendering to Quicktime format fromPremere Elements 8: The AV sync goes out of whack.
I have tried rendering:
(a). To MPEG - output is fine.
(b). To WMV - output is fine.
(c). MOV - av sync errors
I am assembling about five clips. The first clip plays fine. The AV sync problems starts at the second clip - the audio is a good 3 seconds or so ahead of the video.
Everything is fine in the editing window.
I am running in Windows 7. To make sure it is not the player, I have played the quicktime output in Windows Media and itunes and the same problem is in both.
Has anyone seen this issue?
Thanks.

Hi Steve,
Sorry for the confusion. It a sensible suggestion to identify the input formats and output formats and I would most appreciate your inputs to this issue because I admit that I am really struggling here to get a workflow going.
Input formats:
1. MJPEG 1280x720P at 24 frames per second (from a Panasonic Lumix Camera)
2. WMV 1280x720P at 24 frames per second from output of other programs (which only support wmv output at High def output)
3. MPEG2 1280x720P at 24 frames per second (and sometimes 25 frames per second) from other sources
Target output formats are:
1. Blu-Ray
2. MP4 container format @ 1280x720P for playing on my Apple TV
3. DVD (ordinary plain PAL DVD at 720x576P at 25 frames per second)
My goal is have Pre Elements 8 Project settings in High Def and then to simply target all three outputs from one project so that I do not have to redo all of the projects with different project settings.
Workflow is in two stages:
Step 1 is to create one project for each Chapter and save to disk: The inputs are from all three input formats that I identified above (High Def - MJPEG, WMV, and MPEG2). I would like to edit, mix the audio, and then save each chapter to disk. The format in which I save this is preferably some kind of high def format that can be edited easily at a later time.
Step 2 is to create the Project that is used to assemble each chapter for final output: This is the project where I put in Chapter marks, create menus, etc. The target outputs from this chapter are Blu Ray (high def), AppleTV (high def), and PAL DVD (Standard def).
In all cases, I set up my Project Settings as HDV-AVI for internal rendering because all inputs are high def and most target outputs are high def.
Issues that I am dealing with:
1. I cannot figure out the best export format to go from Step 1 to Step 2. HDV-AVI doesn't seem to be available as an export format. Basically, I am looking for an export format that puts the least strain on resources when they are read in for Step 2 and retains the highest quality.
2. Most of my inputs are 24 frames per second but the internal rendering for Pre Elements 8 seems to be 25 frames per second. Frame rate conversion can be quite tricky and can put significant strain on resources, but it is not clear if this is straining Pre Elements 8 or not. It does seem to be. I am happy to convert my files into a format that puts the least strain on Pre Elements 8 internal rendering and yet produces the best output.
Note: If you ask - why do I do this in two steps? It is because I am always putting a strain on system resources when operating in high def. Unless I am careful, I get a message that Pre Element is "low on resources" followed by a crash shortly thereafter. I have Win7 32 bit, 4 GB RAM, no other programs running, all drivers updated with the most recent version (yes - even the NVIDIA driver) so there really isn't anything else that I can do in this area.
So I am looking for suggestions in the following areas:
1. An alternative workflow that produces the three high def outputs with the three high def inputs defined above that doesn't cause Pre Elements to continually go low on resources and crash.
OR
2. A recommendation for a high def format that puts minimal strain on Pre Element resources?
Thanks!

Encore CS5.1 Motion Jitter when rendering

Hi guys
Im Having problem when exporting on CS5.1 some places in the movie specially PAN & TILT shots are Jittering not clear
Im working on Final Cut Pro on Full HD movie im exporting the movie from Final cut as it is and transcoding with Encore. Im exporting Blu-ray
I know that any file i import to Encore it will render again. so im doing that but when i watch the Blu-ray im not liking the quality
anyone can help me please ??
Thank you in Advance

Encore stops when rendering motion menus

I have a pretty consistent problem when rendering motion menus/project and I don't know how to fix it. Can anyone help?
I've just started to use Encore2, having switched from DVD Workshop 2.
I've got a wedding to author and I've used the useful 'Create Chapter Index' function that automatically creates sub menus. This has worked fine UNTIL I render the motion menus.
There are four menus: 1 x Main Menu, and 3 x Sub Menus.
If I render number 1 sub menu it's fine. It renders all 375 frames (why are there always 375 frames?).
The number 2 sub menu also renders properly.
When I get to number 3 sub menu, it always stops at frame 294 and Encore hangs! Why should this be?
I tried creating another project using the same mpeg file (4.12 GB) but with different menus and the same thing happens!
Any ideas?

Assuming PAL (at 25fps) that would be a 15 second motion menu.

Just guessing: If you used motion thumbnails for chapters or timelines, there could be a "glitch" (corruption) 294 frames into the chapter or timeline the thumbnail video is made from.

Field Flickering when rendering to DVD or TV

I'm running into the same problem over and over again. And I can't seem to figure out how to solve it.
The problem I'm having is:
I load my video using the Matrox RTX.2 card, CS4 recognises this as an Upper Field footage (previous versions always were Lower Field). I edit the video, add some effects, and speed up or slow down some files.
Now, when rendering this to DVD Mpeg (or any other DVD compatible extention), creating the DVD (in Encore CS4) and burning it to a PAL DVD format then playing it on TV the slowmotion parts and speedups are Flickering back and forward (the usual field problem)
I've done everything to check it.
- I rendered everything upper field
- I rendered everything lower field
- I changed footage in Premiere CS4 to upper and lower
- I rendered in AVI, MPG (DVD and Native)
- I rendered on a PC using the DV codec (so without the Matrox Card)
- I rendered on a Mac with Premiere CS4 (and a Blackmagic card)
- I done Interpret footage inside Encore with all the variations above
On the end it came down to this, I had to remove the fields in Premiere, I rendered without fields. Now, obviously it's not jittering anymore, but it is less sharp and smooth (because it's more flat and half the frames it supposed to be). That is a solution for now, but not on the long run. Premiere CS3 and previous never had any problems with fields, as long as the production pipeline stayed the same it's no problem
- I also checked the sequence settings
Does anyone has these kind of problems, or does anyone know how to solve this? I tried on 4 systems.. different from eachother.
Thanks in advance,

Try without using anything Matrox related. Likely your problem disappears.

Writing video vs conforming to mpeg 2 when rendering?
