I wanted to retain the interlacing as I prefer to let the playback device do the de-interlacing, and this software makes it a breeze to do so.Īdditionally, I had other material where I only wanted to convert the audio, due to PCM on a mono video soundtrack from the 80's being overkill to say the least, so the option to copy/passthrough the video track was an added bonus. With web optimized, they can start a transcode of every format at the same time, while the upload is taking place.I've been using XMedia Recode to back up tons of old video material which is interlaced. Therefore they cannot even start the transcode until the full file is finished uploading. They cannot do that until they have ALL the file header information. They transcode your upload to many different resolutions and possibly frame rates. But what they (Youtube) are complaining about is that the file is not in "web optimized" format. Sadly, Hitfilm does not have this feature. What really happens in the file gets encoded and written to disk and once the encode is done the header is written to a separate file and the video contents are then copied/appended to the header information. Many encoders have a feature to put the header at the front of the file.
This is a problem for streaming since the information needs to be known before playback. More than just frame size and frame rate. When a file is being encoded you do not know the length of other information for video content headers. In the MOV/MP4 container format the video header can be at the front of the file or at the end of the file. Every time I try to upload a YouTube video straight out of HitFilm with the YouTube preset, YouTube always says something along the lines of “this video is not optimized.” Handbrake seems to be doing some additional magic.
