2020年10月13日 · Max compression ratio would be using temporal compression (long gop). x264 in lossless mode, or FFV1 using temporal mode would typically give highest compression ratio. Typically ~50-75% the size of intra (I frame) mode vs. something like lagarith or YULS (the latter two are I-frame only)

2024年4月28日 · Two popular codecs are FFV1 and H.264/H.265. In this article, we will compare these two codecs and discuss the pros and cons of using each one. We will also cover the topic of lossless vs. Huffyuv encoding and provide some subtitles for further clarification. FFV1. FFV1 is a lossless video codec that is part of the FFmpeg project.

2020年4月29日 · JPEG 2000 or FFV1 are both good choices. JPEG 2000 MXF is used by the Library of Congress: https://www.loc.gov/preservation/digital/formats/fdd/fdd000206.shtml. And FFV1 in AVI or MKV is accepted as archival formats: https://www.loc.gov/preservation/digital/formats/fdd/fdd000341.shtml. Don't use H264.

FFV1 (short for FF Video 1 [1]) is a lossless intra-frame video coding format. FFV1 is particularly popular for its performance regarding speed and size, compared to other lossless preservation codecs, such as M-JPEG2000.

2024年5月8日 · How do I encode videos to FFV1 using ffmpeg? Which version of it is the best one to use? Is it smaller than H.264 lossless, H.265 lossless, and Huffyuv?

2021年9月11日 · FFV1 is faster and more effective than x264 Lossless. Cineform "Visually Lossless" is extremely fast and size vs quality may be adjusted in very large limits. FS modes are "Film Scan" they where introduced as maximum possible visually lossless quality modes that preserve grainy film and video structure.

2024年2月24日 · FFV1 is a video codec developed within FFmpeg. It is lossless, meaning that it compresses video without introducing quantization degradations. Therefore, FFV1 is a good choice for archiving and preservation. A lossless codec comparison found FFV1 to be the "most balanced", offering "relatively good speed and high compression".

2020年3月1日 · FFV1 is intra-coded so each frame is compressed independently of other frames; HEVC is typically inter-coded. Assuming you're using libx265, you have to add -x265-params lossless=1 for true lossless mode (-crf 0 isn't). At the end of encoding, x265 should print a line displaying lossless compression ratio.

2020年5月5日 · FFV1 is not part of the Motion Picture Experts Group standard. H264 is. H264 can be played on hardware devices. At a high level h264 throws out buckets of data and has an adjustment of how much damage you want to do. FFV1 does not.

2016年10月25日 · If you need to digitize and archive analog sources, then you should consider using FFV1 as that is the new darling format of the digital archival and preservation community. gour October 31, 2016, 8:01am
