MPEG Streamclip - good but slow?

Further to advice from Winston and a few others on this forum, I am trying out converting some of my videos using MPEG Streamclip, latest beta release on Windows XP.
My only comment is that it seems to be a bit slow at converting, about 10 minutes of video an hour. This is for a Standard Def TV programme recorded as dvr-ms and converted using Nero to MPEG at approx. 8Mbps before being put into MPEG Streamclip to convert to mp4 using h.264 at approx. 3Mbps.
My environment is Windows XP running on a virtual machine on Microsoft Virtual Server on Windows XP on a PC with an Intel Core 2 Duo 2.4GHz processor, 2 x 1GB 800MHz memory, 7200rpm 300GB drive for OS and 7200rpm 300GB drive for virtual machine. I use virtual machines as this gives me total separation of video processing from my actual machine, which acts as a file server on my network, and I have control over what resources it uses inc. processor.
Using tools such as QuickTime, iTunes or Videora, I get much quick processing, around 2 to 3 times quicker.
My question is do others who use MPEG Streamclip find it slower? Would running it on a multi-core processor help?
I don't mind it being slow as it seems to be generating video which plays well on my Apple TV, even when streamed.

My question is do others who use MPEG Streamclip find it slower? Would running it on a multi-core processor help?
John, the main reason streamclip is slow is because it multi-passes, a lot of other software simply two-passes at best.
Streamclip is not substantially quicker on a multicore computer, indeed none of the software I use takes full advantage of the hardware I have. Very roughly speaking all the encoding software I use, encodes PAL SD at about twice real time per pass. However one advantage of quicktime is that I can encode multiple movies together without increasing encoding time all that much (up to about 4 movies) whereas with software such as streamclip I can only encode one movie at a time.

My 1st Generation time capsule won't connect to the internet thru a new motorola sb6121 - get continuously flashing yellow light. Using a router in between the modem and capsule yields good but slower connection to internet. Any thoughts?

Thanks for your response
Let me give the history - I started with an Apple Express being fed thru a D-Link EBTR 2310 cable Router from an RCA DCM315 Modem (Pure). Comcast service all the way.
Got the 1st generation TC in 2008 and merely replaced the Airport Express with the TC. Worked ok
A year or two ago I did try removing the modem and feeding the TC directly from the modem. Resulted in the same condition I have now - Continuous flashing amber on the TC. So I put the router back in the chain.
Some time later, at the recommendation of a Comcast rep, I replaced the router with (a Belkin F5D 5231) to see if speed and dropout problems would be improved. I thought it helped some at the time but now I am not so sure.
Last week I decided to see if a new modem would help with download speeds. So I got another pure cable modem (Motorola SB 6121- high on the Comcast recommended list).
Got up and running easily with Comcast help and with the modem connected directly to a computer.
Next I put the TC in the link and again could not get past the TC continuing to flash amber. Although I did get connected to the internet with this configuration I lost connection two both of my printers - one connected by USB and the other wirelessly to the TC. Again everything works fine when I put the Belkin router back in the system.
However with the router in there, the modem shows the downstream connection to be 10/100 ethernet speed. (Modem light changes color for indicating speeds.}
I have gone thru all of the combinations of powering down/ up, but all stays the same.
I can live with what I have but something still doesn’t seem right.
Thanks again

Urgent!! Problems muxing .m2v files and audio!! MPEG Streamclip/Compressor

Hello!
I am under an urgent deadline to upload a short 6 min documentary clip for a client to review for screening this week. The footage was shot in 1080/60i HDV.
Usually, I find the best quality and fastest way to do this is to export directly from my FCP sequence using the '150 min Best Quality' DVD settings in compressor to get an .m2v video file and .ac3 audio file. Then I open the .m2v files in MPEG Streamclip which links it with my .ac3 file, then do 'Export MPEG with MP-2 audio". This gives me a single, muxed file that I can then upload to YouTube or Vimeo.
However, with this project, when I open up my .m2v file in MPEG Streamclip, it's recognizing the .ac3 file and I can see the info for it in the MPEG Streamclip window, but when I play the file in MPEG Streamclip or mux it, I don't hear any audio. Furthermore, after about 5 seconds into the clip, the playhead will continue moving, but the video will freeze, then maybe pick up again later. The .m2v video will play back smoothly in VLC player or Quicktime player, but not in MPEG Streamclip.
I've tried exporting different little sections of the timeline to see if maybe I had some corrupted footage or whatnot. I even exported a small clip from an older HDV project to test. But no matter where I export from, I am running into the same problem. I can bring the .m2v file and .ac3 file into DVD Studio Pro and burn a DVD with no problem, but I can't mux them. If I build the DVD file in DVD SP and try to open the .VOB file with MPEG Streamclip, I get the same problem. I even tried using a different software to mux (ffmpegX) but to no avail. When I try with ffmpegX, it either tells me I'm dropping frames, or if it works and it muxes it, when I open the MPEG file, it'll stutter at about 5 seconds in as well and I can't hear any audio, even though there is supposed to be audio in the muxed file.
I think I might have updated my Quicktime a few days ago with the system update, and maybe updated a few other things, so I don't know if this has any bearing on the problems I'm running into. But I was able just a few days ago to export HDV 1080/60i using this workflow without any problems.
I realize I have other export options, but this always seems to me to be the best quality and fastest way of doing it vs. encoding an H.264 which, on my machine is RIDICULOUSLY slow...I need to be uploading multiple versions of the cut to the client, and really need help! Thanks so much in advance!
J

what you want is an m2v program file. Export a reference copy from FCP (uncheck Make Movie Self Contained") That's very fast. Bring it into Compressor. In the settings panel find the MPEG-2 settings folder. Select Program Stream. Adjust to your liking and run. The audio and video will already be "muxed" when it's done and using compressor 3 you can set it to upload to YouTube, Mobile or similar sites.

MPEG1-DV conversion using MPEG Streamclip. Help!

I am having problems converting an mpeg1 movie clip for editing in iMovie.
I recently recorded a concert on my Sony DCR-HC40 camcorder. The majority of the concert was captured to cassette in DV-PAL format (720 x 576, stereo, 48 kHz at 25 FPS).
However, the final third of the concert was captured on the camera's MemoryStick Duo in MPEG1 muxed format (320 x 320 at 25 FPS). The clip is 84 Mb in size.
I want to convert the mpeg clip into the same format at the cassette footage so that I can seamlessly splice the two sets of footage in iMovieHD with as little depreciation in quality of image and sound as possible.
So far I have simply used the 'export to DV' command from the File menu in MPEG Streamclip. But this produces a noticeably crackly-sounding depreciation in sound quality and no improvement in image quality - rather the reverse infact, since when viewed in the larger Quicktime window, the clip shows up the poorer resolution of the original clip.
What do I need to do to get the original mpeg clip to as near a quality as the cassette footage, for editing and burning onto DVD for display on a TV?
Any guidance would be much appreciated.
BTW, I am running Tiger 10.4.3 on a Pb G4 (QuickTime 7.0.3/iMovie 5.0.2)
PowerBook G4 17 1.5 ghz 512 MB Ram Mac OS X (10.4.3)

mpeg1 footage is only fit for showing on screens no larger than an iPod photo or mobile device?
MPEG1 is usually encoded with low resolution and rather low bitrates so the quality is often rather poor.
However, MPEG1 CAN be encoded with DVD-like resolutions and bitrates so the quality CAN be quite good (MPEG1 doesn't support interlacing like MPEG2, though).
It would be a shame to lose the footage as it was part of a concert of Handel's Messiah.
One option could be to do minimal edits to the MPEG1 with MPEG editors like MPEG Streamclip and burn it as a VCD or DVD (they both CAN have the same video although DVDs rarely use it). Then you'd preserve ALL video quality there is.
...but this won't work with your 320x240 video because the VCD/DVD compatible resolution is PAL 352x288 or NTSC 352x240. So you'd need to re-compress even your 320x240 MPEG which degrades quality.
So your best quality option is to watch the MPEG1 on a computer monitor via MPEG Streamclip, QT Player or some other viewer.
Or, you can convert to DV and blend it with the high quality DV tape material. Converting MPEG to DV should not much or at all degrade quality because DV is a much higher quality codec than your MPEG1 source.
Bit Rate: 0.73 Mbps
Duration: 0:16:16
Data Size: 84.79 MB
That's quite low. A DVD uses about 4-6-8 Mb/s and a low quality low res VCD uses 1.1 Mb/s. So your MPEG1 quality can't be very good to begin with.
Audio Tracks:
192 MP2 mono, 32 kHz, 32 kbps
That's very low, too. Even a low quality MP2 often uses 192 kb/s. And the 32 kHz must be resampled to 48 kHz for DV or DVD use.
when played, either via streamclip before conversion, or in QT (I don't have QTPro) after conversion to DV, distorts at quite low levels in a way that a QT movie from cassette does not.
I'm afraid that there is not much you can do if you hear the distortion even BEFORE any conversions. Some dedicated audio processing app might soften the distortion but I wouldn't count on that.
FWIW, you might try to convert using the "Low Level" audio. From the MPEG Streamclip guide:
"For MPEG audio tracks (MP1, MP2) two different audio levels are available for playback and conversion to MOV, DV, AVI, MP4 and AIFF: "High Level" and "Low Level". You can choose one of these two levels using the "Audio Mode" pop-up menu. The default level is "High Level". Use "Low Level" if, and only if, the converted movie or AIFF file shows an excess of volume."
you also mention that re-compressing with iDVD will further degrade quality. Is this true of both types of footage (mpeg->DV & DV cassette)?
MPEG2 compression used in video-DVDs will ALWAYS degrade quality. High quality material (such as DV) tolerates this better so you might not even notice it. So you should use high bitrates if you want to convert and burn the low quality MPEG1-converted-to-DV material as a DVD (with iDVD use Best Performance or don't exceed ~70 minutes with Best Quality).
would I need to get Roxio Toast? What is the difference between this and IDVD?
Toast 7 can be forced to burn non-valid DVD resolutions as a video-DVD (MPEG Streamclip can be used to prepare the MPEGs) with no re-converting or quality loss but those DVDs are not guaranteed to work on standalone DVD players so I'd not use that route.
Basically, what I'd like to acheive is a nicely-edited home movie with titles etc, to put onto DVD & VHS, of a 2.5 hour classical concert, in as good a quality, audio/visually as I can, from the two types of footage, spliced as cleanly as possible. The footage is continuous, but the media changes from cassette to mpeg at a certain point.
Don't exceed ~70-75 minutes with iDVD because after this the quality starts to drop. Toast 7 can burn somewhat longer high quality DVDs than iDVD because it uses compressed AC3 audio so it doesn't "steal" bandwidth from video as iDVD does with its uncompressed PCM audio. But compressing that low quality audio might not be a good idea either!

MPEG streamclip export settings

I realize this is not an MPEG streamclip forum, but there is a FCE question embedded in my post somewhere. I'm converting M2T HDV files in MPEG Streamclip to edit in Final Cut Express. I've used several different export options in MPEG Streamclip, but all of them are requiring rendering in FCE. What is an export format in MPEG Streamclip that I can edit natively in FCE?
Any help would be greatly appreciated!
Katie

When I select export to Quicktime there isn't a 720x480 Anamorphic frame size. There's 854x480 in both the 16:9 and unscaled options, and there's a 720x480 DV-NTSC frame size, but there isn't one that says both. Also, the default compression is Apple Motion JPEG A: I don't see a DV-NTSC codec in the drop down menu for compression. Is there something I'm missing?
Thanks for enduring!

Import .m2t into FCP directly? Without MPEG Streamclip?

So right now FCP will not import .m2t clips directly?
Could Apple consider putting this on their "to-do" list? Because we had the option of switching from PC (Vegas) to Mac (FCP) about 1 year ago, I looked at the MPEG Streamclip solution, and I pegged it as too much of a hassle.
We have about 2 TB of video data stored on portable NTSC drives, and we'll like to access any of it in future FCP projects. Conversion (even if its lossless) is a big issue.
Are there any plug-ins which would allow FCP to recognize this format, so we don't have to convert everything? Everything else (read-only NTSC support), sharing video across high-speed networks and buying Mac hardware is not a problem.
Apple! We would have switched a year ago if not for this! Am I missing an obvious solution?
Thank you,
-Gord

I was extremely happy to find it, and we were able then to try using FCE on some footage. I'm not dissing MPEG Streamclip. But this is something I expect would be a lot of value to people working in mixed environments.
Its not just our backlog of media, and our current projects expecting .m2t source files. It looks like we'd have to halt all capturing on PCs because their software captures to .m2t files. Instead of a smooth migration with new projects we'd have to spend a fortune on Macs, instead of growing our way into FCP.
Is it possible to capture HDV to QuickTime on a PC? Thanks for your comment.

Mpeg Streamclip question

Hey all,
I realize that this isn't an Mpeg streamclip forum, but I need to rip some DVDs and spit them out as QT's to use in FCP.
For some reason, when I import the DVD files into Mpeg streamclip the viewer window slices off a bar on the right of the frame. To be clear, the image isn't missing any picture, but rather it resembles a full frame 4:3 style image with a black bar on the right frame. I wondered if this was just a glitch in the preview window, but when I output a QT sample, the rendered video also has this black bar.
Oddly enough, this seems to happen at random and only with certain imported DVD files from time to time. The DVD I am attempting to rip is a 16:9 aspect ratio, and all of the settings are default as the problem occurs when importing the DVD files, before any actual settings are changed.
If anyone is knowledgeable about Mpeg streamclip and could help me out, I'd appreciate it.

Anyone out there?
My issue is persisting and has caused a total hault to productivity.
Once again, when I import ripped DVD files in to Mpeg stream clip, either via 'open files' or 'open dvd' the image becomes 4:3 in the viewer and leaves a glitchy and empty bar/space on the right of the viewer, when this is output either as QT, DV etc.. that empty space becomes a black bar in the output video.
I was able to successfully output a 16:9 DV clip only once by selecting 'open DVD' as opposed to 'open files' and this seemed to do it but this only worked with this particular DVD.
Any help would be appreciated.

Equuim P40-10X: WLan reception is very good but extremely slow

Hi
I have just bought a Equuim P40 - when I connect it to wireless broadband the reception is very good but it is extremely slow when it comes to load the pages from the internet - any suggestions as to how to rectify this ?
Thanks !

Hi
Its not easy to say why the notebook loads the webpages slowly.
Mostly the websites load slowly because of the big data amount.
If the pages use any flash animations or there is a big traffic on websites the serve could be overworked and the sites loads slower.
Also if the antivirus software is enabled and controls every data transfer the websites could loads slowly.
As you see, many different factors can affect the page loading!

Best Quality Export Settings in MPEG Streamclip to Edit HD Video in iMovie

Hi,
I import video from data DVDs and regular DVDs and edit the videos in iMovie. In the past, I've always used MPEG Streamclip because it can read the native DVD VOB format. I then use the "Export to DV" option in MPEG Streamclip which exports a .DV file readable by QuickTime or iMovie. These are large files, but it is my understanding that this is best quality for editing.
Now I have started to receive HD Videos. When I use MPEG Streamclip the same way, it reduces the HD video into a windowbox 720x480 video loosing all HD resolution.
I've done some research online and apparently MPEG Streamclip's DV export options are pretty limited and other people have said to use the "Export to MPEG-4" or the "Export to QuickTime" which are more configurable. Each of these requires a Compression Codec Selection. Some have said to use H.264, but I've also read that you should not compress with H.264 if you're going to be doing editing.
I do not care about file size, I want maximum quality. The incoming DVD video is 1280 x 720 (HDTV 720p), what Compression selection do I select in MPEG Streamclip for "Export to MPEG-4" or "Export to QuickTime" to maintain the best quality for editing in iMovie? I appreciate your help!
Jerry

Use Apple Intermediate Codec for best quality and best editing performance.
If you have Final Cut Pro installed, you may have additional good options like ProRes 422.

Are my settings correct for .m2t transfer through mpeg streamclip?

hello,
i shot a video on the **sony hvr z7u** using compact flash cards and the video was shot on 1080i ...all the files are currently in m2t...
i used mpeg streamclip and used the follow settings:
-apple pro res 422 codec
-100 percent quality
-uncompressed sound
-frame size: 16:9
-interlaced scaling was checked
are these acceptable? some of the footage doesnt look good with dark colors, but it might just be the way it is shot...
thank you!

The Holy Grail in M2T conversion. Say it 3 times: clipwrap clipwrap clipwrap
The only program that easily rewrap m2t files into QuickTime movies Faster than transcoding
No generation loss. I have an nNovia Digital Drive to record my HD files from a Canon XH A1 camera. The M2T files were horrible to work with. No converter worked. Sound did not sync, Video artifacts, unusable. I downloaded trial- converts first minute and it worked GREAT! Bought it $49.99 very fast conversion. NO LOSS! I am in love! http://www.clipwrap.com

MPEG Streamclip 1.5

MPEG Streamclip is a high-quality converter for MPEG files and transport streams.
MPEG2 conversions require the $20 Apple MPEG-2 Playback Component.
http://www.alfanet.it/squared5/mpegstreamclip.html
http://www.apple.com/quicktime/mpeg2/
New in this version:
- The new files that can be played, edited and exported are: MOV, DV, AVI, DivX, MP4; to open DivX files you have to install either the DivX codec, or the 3ivx codec, or the XviD codec. You can also open WMV files, if you buy Flip4Mac's WMV Player.
- You can set the 4:3 or 16:9 flag for DV export (useful for iMovie HD).
- You can export in ISO MPEG4 (MP4) format. You can use the H.264 codec, if you have QuickTime 7.
- Built-in "Save as AVI" feature.
- You can change the frame rate of the exported file, with optional frame blending.
- QuickTime 7-style AIF files are recognized.
- While in full screen mode, you can zoom the picture with the up/down arrow keys.
Disclaimer: I'm just a satisfied MPEG Streamclip user

1.5.1b1 is out
Oh, great!
Just after I sent a report about the bug in two-pass encoding it was already solved!
BTW, now MPEG Streamclip 1.5 can convert also DV material 4:3 <-> 16:9 while preserving interlacing! It can do the conversion with letterboxing or without letterboxing (but with cropping, of course).
For more details, check:
http://www.sjoki.uta.fi/~shmhav/SVCDon_aMacintosh.html#43-169
iMovie HD deinterlaces while doing its own 4:3 <-> 16:9 conversion and the colors are washed-out -- MPEG Streamclip does all this with good quality!
I wonder why Apple hasn't hired the MPEG Streamclip author. But, on the other hand, a corporate management could ruin all this...

MPEG Streamclip on Lion?

Guys, tearing my hair out hear.
I need to rip a project from DVD I did a while back. But every time I try to Export the VS file to Quicktime I get the following message "Error: Can't Create The MOV File".
I'm using the latest version of Lion on an Intel Mac Pro, along with MPEG Streamclip 1.9 3b7.
I have checked that I have all the MPEG2 Components installed (Apple MPEG2 CODEC.component & Quicktime MPEG2 Component).
I checked out the MPEG Streamclip website and followed their instructions to install the components again from my Final Cut Studio Disks but when I double click the PKG file from my original Final Cut Studio disk I can't use it as it was for a PowerPC application. I have the upgrade disks for Final Cut Studio 3 but these don't hold the necessary PKG's!
The thing is, my Quicktime 7 is the PRO version. So, should this not mean that I should be able to convert files using MPEG Streamclip?
What else can I do?

I was scratching my head about this and realized something about your original post, you said you had the MPEG2 installer but it complained about it being PPC only.
I guess the solution will run you $20, you need to install this:
http://store.apple.com/us/product/D2187Z/A
Your MPEG2 library is the wrong version, you need the one for both PPC and Intel.
If you read the note from Streamclip, although lion has MPEG2 built in, Streamclip can't use it and you need to install the external library, which is the one in the URL, I think it's version 6.4.1, which adds the support into QT7 Pro, which is what you need, intel based.
Good luck.

Mpeg Streamclip, GOPRO HD HERO

What are the best settings in MPEG STREAMCLIP to convert 1080i GOPRO mpeg4 video files to Pro ResLT for editing in FCP6?
Bueler?

I am shooting using the "r5" setting on my HD Hero which is 16:9 1080p at 30frames/sec.
There are myriad settings with MPEG streamclip - For Example: I assume that when exporting to FCP6 I want to "export to quicktime" under the FILE menu - correct? - once in the "Movie Exporter" pane I select "Apple ProRes 422" under Compression - ProResLT is not listed on my system. The quality slider is set to 50% but I have been moving it to 100% - is this a good idea or not necessary? Next comes Frame size - should I keep it unscaled? Should I enter something in the "frame Rate" box? Should I check "frame Blending" and/or "better downscaling"?
"interlaced scaling?" Should I deinterlace video at this point or do it later when I export from FCP6 at the later part of the workflow?
The rest of this "movie exporter window" I think I understand.
THanks for anything you can send along.
Best,

MPEG Streamclip - good but slow?
