I’m a newbie just getting started with video editing. I got the “Vegas Movie Studio HD Platinum 11 Visual Effects Suite” that comes with hit film. My Panasonic HC-MDH2 camera records mts files, and they work fine in the Sony Vegas software, but when I bring them into the editor in hitfilm, slowa to a crawl. One click on the timeline and it may be 30 seconds before I can do anything again. If I make a composite and work with it, it’s not too bad, but in the editor, it’s unusable. I’ve been taking them into SonyVegas, saving ous as mp4 and then bringing them in and they work fine then. Any ideas on why HitFilm is so slow with mts files in the editor? I have loaded it on two machines and had the same issue on both.
In order to make clear the causes, you need know the supported format and codecs of the HitFilm.
The following formats are supported by HitFilm:
Video: Quicktime, AVCHD, AVI, M2T, M2TS, MOV, MP4 (AVC/H264 & AAC), MPEG-1 & MPEG-2 (TS, PS, MPE, MPG, MPEG, M2V), MTS, MXF (DVCPro HD), DV, HDV, WMV
Audio: AAC, MP3, M4A, MPA, WAV, WMA
Its quite likely that in addition to the .mts file, there is some Dolby audio connected to your clips. Dolby formats are not supported by HitFilm at present, and that is likely the cause of the issue
As you mentioned, the issue is likely with the audio, so the important information is the format of the audio. If your audio is in a Dolby format, such as AC3 (this is true of all AVCHD footage), then it won’t be compatible with HitFilm yet. As I understand, in some cases the extension changes from .mts in camera to .m2t when you capture to your computer, and they are essentially the same format. But the format of the video isn’t that critical, its the format of the audio that is more relevant.
However, MTS files are inherently a slow format so I’d always convert to something more manageable – Quicktime Animation is a good option as it retains full quality but is nice and snappy in HitFilm. MP4 is also fast, but it compresses the video as well so you’ll risk dropping quality.
