Is often considerably higher than the default size of a simple queueĮlement. With pipeline stalling in non-trivial pipelines, because the encoder latency Some settings, including the default settings, may lead to quite After this the option-string property isĪpplied, followed by the user-set properties, fast first pass restrictions and If a preset/tuning are specified then these will define the default values and The recommended way to set a profile is to set it in the hardware platforms) a more restricted profile/level Which is fine for most software players and settings,īut in some cases (e.g. Otherwise, if entropy coding is enabled orĪre allowed, then Main Profile is in effect, and otherwise Baseline profileĪpplies.
If is enabled, then High profile is used.
The H264 profile that is eventually used depends on a few settings. In which case the property controls much of the outcome, in that case is the maximum bitrate. Is to obtained in multiple (2 or 3) pass encoding.Īlternatively, one may choose to perform Constant Quantizer or Quality encoding, This will similarly be the case if this target bitrate In case of Constantīitrate Encoding (actually ABR), the will determine the quality The property controls the type of encoding. I've been encoding MPEG-2 for almost 20 years now.This element encodes raw video into H264 compressed data,Īlso otherwise known as MPEG-4 AVC (Advanced Video Codec). I can try to help you with whatever I know, or point you towards info that I'm aware of. There's still a huge audience using MPEG-2, and probably will for at least another decade. Broadcasters, anybody that distributes optical media (DVD, Blu-ray). Sort of like Handbrake compared against Hybrid.Ĭ. I know I read in-depth info online in the 2000s, and I actually still have lots of info that I saves (ripped out pages) from Broadcast Engineering magazine.ī. There should be many notes about this online. I thought about a quite a bit when x262 was started, but that project is abandoned for years and in to real finished state.Ī. I have no experience with encoding Mpeg-2 using ffmpeg which seems to be the only free and cross-plattform encoder for MPEG-2. I have no clue about the container overhead (in mpeg/vob/m2ts/mkv/mov) to properly calculate the target size of Xpass encoding.ī. (, 22:53)Selur Wrote: Problem with Mpeg-2 is:Ī.
