This guide introduces the quickest and easiest way to convert TS video to MP4 format, so that you can play TS video on portable devices and media players freely. 
What is TS file? TS is abbreviations for Transport Stream, which is specified in MPEG-2. And it is a standard format for transmission and storage of audio, video, and data, and is used in broadcast systems such as DVB and ATSC. Transport stream specifies a container format encapsulating packetized streams, with error correction and stream synchronization features for maintaining transmission integrity when the signal is degraded. What problems we have with .ts video files? Hi, I am looking for a tool able to convert some ts files to mp4. These ts files contain a H264 (mpeg4 avc) video stream and a AAC sound track. Only the ts container shall be converted to mp4, not the video nor audio stream which shall stay untouched. I tried many tools but all of them encode the video and audio stream. avidemux should be able to do the job since there is an option "copy" for both video and audio but unfortunately it always crashs. Any great program recommended? And how to encode these videos without de-synchronisation. As .ts is not compatible with many portable devices and media players, if you would like to easily playback these .ts video files you have recorded, you'd better transcode these TS videos to a common format which is suitable for watching, like the MP4 format.

Fall in trouble when editing Sony 4K XAVC videos in Premiere Elements 13? If so, follow the easy workaround here. Adobe Premiere Elements with stunning features is popular video editing software for us. The point here, sometimes, you will find it's a painful experience when loading Sony 4K XAVC files into Premiere Elements 13. And there are some frequently asked question quoted as below. 
Q1: Does Premiere Elements 13 Support 4K video? Somehow my previous question disappeared. Does this program support 4K to burn to 4K Blu Rays? Q2: Sony F55 4K XAVC footage to Premiere Elements 13 crash? I've tried to get some 4K XAVC footage from an F55 to work in Premiere Elements 13. It imports, but when I try to do anything with it, it crashes. As far as I know, Premiere Elements 13 has project presets for the video with the resolution of 3840 x 2160 (a 4K resolution) under NTSC only. It also offers export of the 3840 x 2160 resolution under Publish+Share/Computer/XAVC-S. However, there is no burn to Blu-ray with any 4K resolution. The compatibility between 4K videos and Adobe Premiere Elements is still an unsolved mystery in that some persons can import 4K videos into Elements, while the others can not: On the one hand, the computer configuration and operation environment should play an important role on this aspect. On the other hand, bypassing 4K issue, XAVC, as a newly high compressed video format, is not supported by most NLEs, including Premiere Elements, FCP, iMovie, Avid Media Composer, iPhoto, etc. So to get rid of the issue, the first step we need to do is to make 4K XAVC files editable in Premiere Elements 13. Here we suggest you give a go with Pavtube XAVC Video Converter for Mac or Windows which work smoothly in converting Sony 4K XAVC to a more "edit" friendly codec for Premiere Elements 13 like MPEG-2/AVC MOV. The most attractive thing is that it can downscale your 4K videos into common 1080p so that NLEs can afford well. If you're troubled by the similar problem, just download the right version and follow the guide below to start conversion. (Learn more: Top 3 Best XAVC/XAVC S Video Converter for Mac Review) Before processing: Back up/Transfer the 4K XAVC footage to Mac computer - copy the whole video folder to your computer hard drive, not just the individual .xavc files. Step 1. Install Launch the Mac XAVC to Premiere Elements Converter. Click "Add Video" and browse to Sony XAVC clips and the software will add it to file list. Repeat the operation to load multiple XAVC videos. Or you may click the "Add Folder" button to import all the XAVC files in the file structure. 
Step 2. Click on "Format" and choose "MPEG-2 (*.mpg)" or "MOV(AVC) (.mov)" from "Adobe Premiere/Sony Vegas> " as the best codec for editing Sony 4K XAVC in Premiere Elements 13. What's more, you can also transcode XAVC to FCP, iMovie, Davinci Resolve, Avid for editing or to QuickTime and various multimedia devices for playback. 
Step 3. Click on "Settings" to redefine output quality. You can also set a different video resolution (1920x1080/1440x1080/1280x720/720x480), frame rate (24p/30p), bitrate, audio channels, etc. For users who would like to retain exactly the same settings (without any quality loss), set target settings the same to source video. Step 4. Click "Convert" to start transcode 4K XAVC to MPEG-2/MOV for Premiere Elements 13 editing on Mac/PC. Once you get the converted .MOV/.MPG file, you can import videos to Premiere Elements. Now you can edit your Sony 4K XAVC videos in Premiere Elements 13 with ease. Read Also:

Does iMovie 11 properly handle 60fps video now? If you are currently having 60fps files and iMovie import issue, the post will tell you why iMovie not importing 60fps HD videos and offer the best and fasest solution. 
Got one camcorder, like Sony NEX-5N, NEX7, A99, A65, Panasonic HC-V720, HDC-TM90 to record 1920*1080 Full HD MTS footage up to 60fps (50fps for PAL) and have met the incompatible erros when you tried importing 60fps videos to iMovie 8/9/11 for further editing? From googling, we find many users have the same issues: Question1. "Whilst away snowboarding on my most recent trip, I recorded most days in 720p / 60fps (as it looks ultra smooth) and have just over 54Gb of footage; divided into five folders on my iMac (one for each day) with about 20 .mp4 files in each one. I assumed I could put together something decent on iMovie 11. Some Googling revealed that iMovie 10 does not support 60FPS. Is that right? And then how to get imovie easily working with these 60fps video? Any help would be appreciated." Qustion 2. "I am a novice iMovie 11 user. I have footage in a 60fps camera that I imported into iMovie. When I import it, either with or without optimization, the video is very jumpy and the audio doesn't time with the footage at all. But 30fps footage imports into iMovie correctly. Is there any way to import the 60fps video correctly so that I don't have this problem, even if it means downgrading the quality?" In fact, iMovie can't support the format 1080p@60fps because it is a nonstandard frame rate. If you want to natively ingest and edit the 60fps videos in iMovie, you have to firstly transcode 60fps footage it to a compatible frame rate with a native format by iMovie, like AIC. It means that you have to use a professional HD Video Converter for Mac to encode the 60fps video to Apple IntermediateCodec(AIC) yourself at 60p, and iMovie will let you edit a 24p or 30p project. Note that even if you shift your footage to AIC at 60p, iMovie will downgrade it to 24fps or 30fps on export (depending on what you chose), but it still doesn't look bad at all. It will just use the extra frames to make it smoother. If you shoot in 60fps and slow it down to 30fps, you are still using 30 frames to fill 30 frames. It will be much smoother. If you attempt to transcode 60p video to AIC for using with iMovie, we would recommend Pavtube HD Video Converter for Mac - Top 60fps HD Video to iMovie Converter. Main features: This software is best Mac HD Video Converter that can transcode any kinds of HD Video files to Apple InterMediate Codec (AIC), Apple ProRes 422 codec, DNxHD codec, MPEG, WMV, AVI, MOV, etc. for puting into iMovie, FCP, Adobe, Avid, iPhoto, DaVinci Resolve, Kdenlive, Keynote, Aperture 3, etc. NLE's for editing, and enables users to custom video and audio settings like frame rate, bit rate, resolution, sample rate and audio channel at will. These output formats are specially presetted, so the conversion quality is guaranteed, you can get lossless video conversion with this tool.

Step 3. You can click "Settings" to customize the output parameters, adjust the resolution, bitrate as you want.
