Someone shot some footage (9 minutes) and gave me an MOV that plays fine in QuickTime but when I put it in Final Cut the audio is out of sync. However, Matt wrote in with the following problem: Here’s an article that describes this in more detail. ]Īudio that slowly drifts out of sync is often due to a mismatch between the sample rate at which you shot the video and the sample rate at which you captured the audio. Output #0, mov, to 'E:\Video\Capture\f79131488 Nachrichten_temp\f79131488 Nachrichten_out.[ This article was first published in the July, 2009, issue of encoding with ProRes standard (apcn) profile Warning: data is not aligned! This can lead to a speed loss Stream #0:0 -> #0:0 (rawvideo (native) -> prores (native)) So I saw that StaxRip can do ProRes HQ with ffmpeg and I can use my deinterlace filter.įfmpeg.exe -i "xxx.avs" -c:v prores -aspect 1.367521 -an -y -hide_banner "xxx.mov"ĭuration: 00:07:26.88, start: 0.000000, bitrate: 0 kb/s Okay this is probably the wrong codec and the Mac version doas not support 64bit.
ProRes is hardly as bad as MP4 compression, so it will add the least artifacts to your converted MPEG-2 files for editing. Besides staxrip to MP4 (heavily compressed to heavily compressed file format), you could use other tools to convert MPEG-2 to ProRes (a lightly compressed file format - big, but retains as much as reasonably possible), which iMovie will accept. No idea what iMovie does, but hope that it'll convert to MP4 at a sufficiently high bitrate that artifacts are kept to a minimum.Ĥ. and until the final render, do no intermediate encodes that add additional defects and such to your MPEG-2 originals. will open the MPEG-2 files natively, allow you to crop, resize, add effects, deinterlace, etc. that you do to these files over and over will quickly add up and result in mush.Ī GOOD video editing program like Vegas Video, Adobe Premiere, etc. These are typically heavily compressed vs other codecs like DNX or ProRes, so any cropping, editing, etc. Typically, with any format conversion, you'd want to do that at the end of editing if you're working with MPEG-2/MPG/MP4/H.264 formats.
You can try these if iMovie has any issues opening your files.ģ.
There are other free, professional level video editing programs that apparently support MPEG-2 natively. You would have to convert to MP4, which iMovie does automatically with media formats it can convert. iMovie apparently does not natively support MPEG-2 files.
