Mpeg streamclip multipass how many passes

I updated all the goods. So to answer your question the export finished. I am using the most recent Avid software, nothing is linked thank goodness all avid files. So what is weird is, Im not sure if this is new for Avid export but it loops like 3 times and then does the final Making movie to complete the file. Just bizzare how it takes 3 loops to export an H.

Open your export setting, then Format Options , then under "Video" select Settings. In the lower-left corner of the Settings box, you probably have Best Quality multi-pass selected, instead of Faster Encode single pass. There's nothing wrong with leaving it the way you have it, but understand what is happening is supposed to happen. The encoder is analyzing the footage several times and determing the quality needed at each particular moment to keep the quality up and the file size down.

That said - Avid is not a very efficient H. Generally, once all the media in your sequence is Avid-native media, it's best to output a QuickTime Reference, and then encode your H. Sorenson Squeeze is an option that comes with the "subscription" not perpetual with support version of MC. There's also Apple Compressor, and multiple other ones that do a good job as well careful of shady ones though.

The added benefit of this is that once the file is out of Avid, it frees you up to continue editing while the other software does the encode. Exporting with multipass selected doesn't go through a status bar multiple times, it just estimates a longer time.

It will estimate a 10 min time to finish versus a 5 min estimate. It doesn't finish and then start over again. I'm having this same issue. The correct estimated time is shown and it finishes and then just loops around again and starts over again.

If you cancel it's as if you didn't finish exporting and there's nothing left at the end. We are on Mac OSX I assume you are on 8. Sign in Sign in Sign in corporate.

Could someone please, please, please explain hgow to encode an entire movie using MPEG Streamclip not just a single chapter. Use command-F if application does not ask. It seems to me it always picks the "default" one. Is there a way I can select the movie's language version in Streamclip?

Believe it usually defaults to the first listed audio option laid down by the disc manufacturer. That is, the more bitspersecond, the more information about a region of the image can be put into the stored video. The more information, the more accurate a representation of the original. Up to a point.

What may be helpful to understand is that for any content, there's a point at which adding datarate won't improve the image quality during playback. When you add that Youtube or Vimeo is going to recompress your file into something that can be downloaded and played over an internet connection, there's a point at which adding more data in the version for upload is overkill and you've wasted the time to generate it and upload it. The download bandwidth forces the maximum data rate.

Storing the original clips or final edit is a different story. Saving the original quality means you have, well, the original and you can never get better than that. So exporting the final edit in the same format as the original clips is like generating the final edit at that highest quality of quality possible.

Anything more is overkill or you are uprezzing it for some other reason. Back to the point, why compress a video at all? Basically the answer is so that you can deliver it in a practical way over the web, on a DVD and so that it can be played on a wide variety of computers that aren't as honkering as your edit suite or have special software for the particular CODEC the camera used.

MPEG2 is another. As you have discovered, you can generate H. The image quality is pretty much going to follow that the larger the file data rate , the better the quality The size of the playback window affects how it looks.

You may generate a p file but if watched in a sized window, then viewers may never see the difference between the p at 2Kbps versus 5Kbps. As for VBR vs CBR, the principle is that areas of the video that need more data persecond to keep a good looking image e. Multipass is giving the compression algorithm the luxury to spend more time tuning the resulting compressed output so that sections needing more compression time and data rate can benefit from techniques that handle certain things in the first pass and other things in the second pass.

ALso, intermediate information about the image can be stored in the first pass and leveraged in subsequent passes and eventually thrown out. No sense in doing that if there's only one pass.

Lastly, algorithms matter. A file generated by Compressor is not identical to one generated by Streamclip even when the same parameters are used. Some software is better than others.
