![]() Writing application : mkvmerge v8.3.0 ('Over the Horizon') 64bit The original video resolution is completely destroyed.Īm I missing a setting. No matter which Profile & Level option I set in Xmedia Recode the resulting video is coarsely tessellated. ![]() From what I can find it should support Xvid in MP4. So the 64-bit version it shall be.I am trying to recode x264 video in MKV to Xvid in MP4 for a stand alone Daenyx DV2001 player. results indicated that using the 64-bit version of VidCoder will knock about 10.8% off the time taken by the 32-bit version, or, to flip it around, using the 32-bit version will add about 12.1% to the time it would take using the 64-bit version. not taxing the system otherwise in the meantime). same files to convert, using exactly the same settings, and giving VidCoder the run of the computer in both cases ( i.e. The drawback to doing it this way is the obvious one: it takes a lot longer, more than double what I'm used to, but I may get around that by doing batch conversions overnight, to help deal with the impatience factor.Īs a point of interest, I installed both the 32-bit and 64-bit versions and ran a benchmark, comparing the two architectures under identical conditions, i.e. A lot of these files are in the 7,000–10,000 kbps range and I like to compress them some to keep storage sizes manageable. What's interesting now is I actually lowered the bitrate slightly, to 1,500 kbps (I only changed "Target size" to "Target bitrate" in your instructions) and that "steps of luminosity" effect with blacks is no longer present. Before, I would notice a definite reduction in quality (despite not knocking down the transcoded file's bitrate too much and keeping it in the 1,700–2,000 kbps range), most especially noticeable in dark "fades" where I could clearly make out the delineation between the "shades of black" being used for the fade effect. ![]() redoing H.264/MPEG-4 AVC but just lowering the bitrate. Where I notice it the most is when I'm recoding a file using the same encoder and file format, just for the purpose of reducing its size, eg. There is a definite improvement in quality with this program and these settings over the way I was doing it before, which was with a different program but I mean in terms of the 1-pass vs. Thanks for this ^, you introduced me to the program as well. Under Settings->Video set the Target size and select 2-pass Encoding. A slower x264 speed preset should help as it tends to allow the encoder to compress the video a little more efficiently, which means for 2 pass encoding a slower x264 speed preset should increase the quality a little.Įasiest: Vidcoder. If you want a particular file size, use 2 pass encoding while specifying the desired file size/bitrate.Ĥ.5GB might be a bit optimistic for a 720p video over four hours long, but you never know. Therefore, you'd use the constant quality mode when you want to set the quality, in which case the bitrate required is unknown, or you'd specify a bitrate for a 2 pass encode and the quality becomes the unknown. ie If you run a constant quality encode, check the resulting bitrate, then use that bitrate for a 2 pass encode, the two encodes will be virtually the same. For x264 encoding, the video will be encoded the same way when using constant quality encoding as it is for 2 pass encoding, assuming the bitrate is the same each time. For a given quality setting (ie Handbrake/Vidcoder's constant quality) the bitrate will vary considerably from video to video according to how hard it is to compress.
