Transcoding AVCHD to MPEG4/H.264 High Definition Video

Does it make sense to transcode the highly compressed .MTS video files to MPEG4/H.264 video in Media Encoder to work more fluid in Premiere Pro CS5.5?
Even though I think my iMac is powerfull as a consumer setup I have some stuttering during playback in Premiere. Will the process degrade the video?

I have now included a G-Tech 4 TB FW800 RAID 0 striped disk array in my setup and editing my video has become a breeze :-)
Thank you everyone for your help! It is really appreciated!

Important quality loss in high definition video in Premiere

Hello
I'm working in a series of high definition clips in Premiere CS4, and I noticed a great loss of quality of the videos after rendering, even without applying any filter or special effect.
All of the videos were captured from a Sony HD camcorder in M2T format through HDVSplit. The M2T videos are perfect, with clear and crystalline images, typical of a HD clip.
However, after rendering in Premiere using the MPEG2 Blu-Ray HDTV 1080i or HDTV 720p format with all of the settings in high quality, the resulting video is disappointing, in no way resembling a high definition video. The same occurs using H.264 Blu-ray format, also with all the settings in "high".
The quality of the video is well below the expected, both in 1080i and 720p.
I didn't use any filter in the edition, just trim, simple transitions and some legends. The resulting video shows a significant loss of quality and definition, which resembles more a trivial SD DVD than a video that was totally recorded in high definition.
I believe that it is a codec problem, but I would like to know if somebody already observed this issue, and if some special adjustment or setting exist that I'm missing.
Any contribution is welcome
Thanks

Do you mean rendering the timeline for playback, or rendering the video with a preset for output? You can start by making sure the quality setting in the program monitor is set to highest quality, not draft, or automatic. You can also check the Maximize Render Quality option. See the following taken from Adobe's website:
Maximum Render Quality option
You can improve rendering of motion, improve deinterlacing, and improve scaling of video. Select Maximum Render Quality in your sequence settings or Use Maximum Render Quality in your export settings.
If the resulting video from an export from Premiere is low in quality, then you need to adjust the bitrate settings, or resolution settings.

Why isn't my high definition video converting to standard definition?

What I'm describing here, I've successfully accomplished many, many times using Premiere Pro CS5 and now Premiere Pro CS6. Now, for the first time ever, it's not working and I'm completely baffled. (This is a high-end Windows 7 64-Bit machine with 16GB RAM running Premiere Pro CS6.)
Here's a basic summary of my workflow. Nothing out of the ordinary here.
1. I shoot my video using a high definition camcorder (the same one I've been working with for the past year or two.
2. I import my high definition video into a 1920x1080 sequence in Premiere Pro CS6.
3. I edit my sequence until I'm happy.
4. I enter and name my Encore chapter markers in the sequence.
5. I create my Encore project and import the sequence as a timeline and set up my menus and such.
6. I build my Encore project, first into a standard definition DVD image file (so I can later burn SD-DVDs) and then build it again into a high definition Blu-ray image file (so I can later burn Blu-rays).
The Blu-ray burn is turning out just fine.
But the video in the DVD burn is all black. I can jump around from chapter to chapter and I can hear the sound, but the video doesn't show up!
I tried this a couple times thinking that maybe Encore just messed up the SD-DVD creation process but I got the same result each time. When I preview the project in Encore, it all looks just right.
So I figured, okay, something's not working when I import the sequence.
I went back to Premiere Pro thinking I'd just export my 1920x1080 sequence into a widescreen standard definition AVI and create a new sequence just for the standard definition DVD.
The exported AVI is black as well!!
I don't get it. Why on earth won't my high definition video convert properly to standard definition?
The high definition sequence looks completely normal in Premiere Pro. What could I possibly be overlooking??
One final note. Just as another test, I copied and pasted the sequence in Premier Pro, truncated it to a couple minutes (the full sequence is 90 minutes long), and exported to a widescreen AVI again.
It just finished, I tried playing it back in Windows, and it, too, is all black, sound but no video.
Like I said, this is nothing new for me. I've done it countless times with other projects. I could really use some assistance with this one.

So I exported my completed high definition sequence to an MP4 and re-imported back into Premiere Pro. Right-clicked it and created a sequence from the clip. Then I imported my chapters from the old sequence into the new one.
I returned to Encore, modified my project to work off the newly created sequence (what a pain having to recreate all the scene links) and voila, it had no trouble making a DVD this time.
So I guess I'll get out of the bad habit of my old routine and create a sequence the "right" way from now on. Funny how we get used to doing something one way and stop thinking outside the box after a while.
Jim, I don't see how that's necessary. As long as I create an Encore project based on a good high definition sequence, I have never had to do anything other than have Encore build a standard definition DVD based on the high definition sequences. It has always done the conversion for me and produced really good DVDs. Once I create a DVD image that I'm satisfied with, I simply have Encore build a Blu-ray image using the exact same project, and that works perfectly as well. I suppose I may be missing something here but it all works and works well, so I don't see a reason to create two projects when one works well.
On a separate note, is it just me or doesn't everybody think it's high time that Adobe offer a feature to import markers from one sequence into another. I can do it automatically but I have to use a macro that I created separate and apart from Premiere Pro. For that matter, I think Encore should also offer a feature to remap all scene links to a new sequence instead of forcing me to fix them one by one myself.
Anyway, thanks to all of you for pointing me in the right direction!

Can now with imovie 1.2.2 and iOS5 edit 1080p high definition video from DSLR cameras like the EOS 5D Mark II on ipad 2?.
That would be great, you would open the door to professional video editing ipad 2. Is there an accepted camera list?.

There does not appear to be a list yet.

High Definition Video on MacBook Pro 13.3"

Hey guys...can't seem to find the answer, despite my best efforts. Can my MB Pro (bought brand new a week ago) appropriately display High Definition Video? In all it's glory? I have a HD copy of the movie Up, and it looks gorgeous, but I haven't been able to find any documentation or reliable info that states without a doubt whether or not its a feature of the machine I bought. Thanks!

I understand the concept that the Macbook Pro's with anything less than the 17" screen cannot display the full HD screen. However what if in my case it is connected to an external monitor. Is there a way to display High Definition thru the laptop onto my 32" TV, or does this still require the use of the 17" MacBook Pro?

Will QT Pro Capture High Definition Video?

Does QuickTime Pro have the ability to capture high definition video? I have tried to do this with a Canon HV10 camcorder, but have not had any luck. I have been able to capture the video using iMovie HD 6.
Thanks
Kurt

Does QuickTime Pro have the ability to capture high definition video?No.

No Application for High Definition Video?

Hi Everyone,
Sorry for being in the wrong section, but I have a new camera with a high definition video and after importing the video I cannot play it as there is no application for it? The camera is a Panasonic Lumix. I have tried using VLC but to no avail.
Many thank in advance!

DVD Player (Applications folder.) DivX, a third-party player may also work. I'm sure you can find others at VersionTracker or MacUpdate. iMovie HD which is part of iLife.

Capturing High Definition Video

When importing high definition video into iMovie HD 6 the last 1.5 to 2 minutes of my movie were not captured. When importing HD video the capture speed is less than real time and thus the video that is running on the camera is ahead of what you see on the computer. I stopped the camera - NOT the import - at the point in time where the camera reached the end of the footage I wanted to import. At this point in time iMovie displays a message indicating that is continuing to cache (import) the rest of the movie - which it did. If you stop the the IMPORT - then my understanding is that the video captured will be essentially stopped at the point you see on the screen.
Any thoughts?
Thanks
Kurt

Maybe you should try using the Scene-Detection Feature in imovie.

High Definition video requires 1GHz G4 or faster...

iMovie HD 6.0.2 (267)
High Definition video requires 1GHz G4 or faster...
It was not evident that I could not use iMovie 6.0.2 on my TiBook. I don't care about HD, I just want to play around with iMovie. I've lost my initial Install disks after upgrading.
I purchased iLife to be able to just play with iMovie.
I can create a project and import video, not images...The buttons don't work. Pull down menus do. Can't drag clips to timeline...
Did I just waste $80.00?
867 MHz PowerPC G4 TiBook Mac OS X (10.4.6) 1 MB L3 cache, 1 GB SDRAM

Did I just waste $80.00?
No, it's probably not wasted...
So while your Mac may not be able to edit HDV it can
edit the "normal" video recorded by most camcorders.
In other words, iMovie HD can do all the stuff old
versions do, but it can do HDV too.
I actually don't even have a camcorder. I just wanted to import .mov files, etc.
There might be some other problem. Here's some topics

High definition video with Geforce FX 5200 ?

hey guys,
can some body tell me if my MSI Geforce FX 5200 T128 is capable of high definition video e.g stretching small video window to full screen, in this mode you see bad video quality is there any solution ?

this is not a vga issue. if u get a video with 720x480 resolution and strength it, surely it will lose quality. for maximum resolution of windows, check the monitor and vga card´s manual for specifications.

High Definition Video playback in Keynote?

Can Keynote play back High Definition Video?
I'm not a video guy at all, so I'm not really sure of what precisely constitutes an "HD Video" file, but I do recall being given some Quicktime files a while back that were larger in file size, screen size and better resolution. These, I was told, were "HD."
Anyway, a client is asking if Keynote supports HD, and I'm at a loss...
- Nolan

I ran into the same problem. I had some picturess that had great detail. I put them into iMovie to get the "Ken Burns" effect, but when I shared them and used them in KN the lost their detail. I called Apple and the tech told me how to get HD images into KN.
In iMovie there are many options as to size and resolution when you use share. I think that I have used HD images stright from Photoshop to KN also. Hope this might help, somewhat late.

Viewing High Definition Videos

iMac 20 inch 2 GHZ
Is it worth paying extra to rent high definition videos vs. standard definition to view on my iMacs 20 inch screen. Is there a noticeable difference in viewing quality? I usually watch videos from about 8 feet away.

Thank you for taking the time to respond.
However, I did not mean to ask if the iMac was capable of playing high definition videos comfortably.
I meant to get opinions on whether high definition videos from iTunes are suppose to look noticeably better than standard definition videos on the iMacs 20 inch screen at a distance about 8 feet. I am thinking that the difference in quality is not noticeable because of the size of the screen and viewing distance.
I rented an HD version of the new James Bond flick and can't see much of a difference in quality between it and a standard definition video of The Office. I don't know if it is just because I am not a videophile or because of the size of the screen and viewing distance? I realize that tells me if it is worth paying extra, but I still would like to know your opinions on the difference in quality that you see.
I apologize for the confusion.

H.264 High Definition playback?

I'm wondering if the new mac mini can playback the h.264 1080p QuickTime movie trailers smoothly?
I did notice this comment with regard to the GMA 950 on Intel's website :
"High Definition Hardware Motion Compensation to support high definition hi-bitrate MPEG2 media playback".
http://www.intel.com/products/chipsets/gma950/
So maybe not h.264-HD but perhaps MPEG2-HD.
Dual 2.7Ghz G5 Mac OS X (10.4.5)

I purchased and returned a Core Solo, as has been reported, it is not fast enough to decode H264 1080p without dropping frames. I tested the Core Duo 1.66 in the store and it seemed to barely get by but did not drop any frames. I was playing the IMAX Deep Sea clip from the Quicktime HD gallery which has high complexity and motion. As a long term solution it makes me nervous especially since the QT page under recommended systems calls for the core duo at 2.0 ghz or higher. I agree the mini is THE media device based on its form factor, all other considerations the iMac is a great deal for the money, but the form factor will absolutely not work in my front projection home theater.
So the question is, when will Apple bump up the Mini to the Core Duo 2.0 ghz and will they ever go back to a real video card? For now I am waiting (with a 1080p projector !) for an update and hopefully a blu-ray dvd drive.... one can only hope.
Apple should also recognize that 1080p content is practically non existent unless you are going to play it from a computer based media device. The iTunes Music Store is in a unique position to propel the 1080p market if Apple updates the Mini and they release movies for download in 1080p res.

Hauppauge High Definition Video Capture

Does anyone have experience of the "Hauppauge HD PVR USB Hi-def H.264 Video Capture Device,high Definition USB 2.0 Video Capture With Hardware H.264 Video Encoders"?
If so what do you think of it?
Leaving aside PVR (it isn't in my opinion as it needs to be connected to a PC for recording) and the over emphasis on recording gaming sessions it sounds as though it might be a handy High Definition equivalent of the Canopus ADVC analogue to digital converter range.
Cheers,
Neale
Insanity is hereditary, you get it from your children

Neale,
I have never used one, nor have I read many articles from those, who have used it. The exception has been some users, who have had issues with Hauppage capture cards, but I do not know of any, who used this device.
Good luck, and wish that I could help, but will follow the thread, in hopes of learning something new.

Burning High Definition Video to DVD

I'm using a Canon HV30 with iMovie '09. How do I save the movies to DVD? Is there a high definition DVD burner that I can buy to save the movies to? If not, what's the point of a high definition camcorder if I can use the functionality? I'm guessing I'm missing something.

Nope; that's the way it is!
Apple would like you to produce hi-def files which you put on your Mobile.Me internet service, or put on your AppleTV, for people to see them.
You can, of course, get an external Blu-Ray burner and buy "Toast 10" to burn your HD files ..or you can burn HD files (..about 20 mins' worth..) onto a standard DVD using Toast or Apple's 'DVD Studio Pro' ..but they won't play on ordinary DVD players, possibly will on old Toshiba HD-DVD players, and should play on Macs.
It's the hi-def wars: burn to disc vs. distribute as (moderately) hi-def H.264/MPEG-4 files.
"..what's the point of a high definition camcorder if I can use the functionality?.." ..exactly!
Sometimes I put them on my Mobile.Me Gallery, sometimes I put them on my AppleTV ..now if only I could get this Serial-ATA LG Blu-Ray burner recognised by my Mac I'd be busy burning ..but which of my friends or relations has a Blu-Ray player on which to play the finished article if I send them a BD disc?
Wake me up again in 4 years' time, when this has all been resolved..
