I recommend you try both trials and see what you like better to make sure they do what you need them to do . Action is decent , and gets updated a lot it ' s also currently on sale . Never had a problem with the program itself recording currently what I use since moving away from Dxtory . I do have to remux the GPU MP 4 files to get them into Vegas , which isn ' t required for the AVI or software MP 4 formats I use FFmpeg with a batch file , remux takes a few seconds each video . Batch file for anyone wondering ffmpeg . exe , the . bat and a remux folder in the same folder with recorded videos for %% a in . mp 4 do ffmpeg i %% a map 0 cv copy remux %%~ na . mp 4 D 3 DGear is functional but very barebones option wise , it also maywill interfere with other recorders when installed even when not running blocking OBS from hooking for example . Other than that no issues that I remember . Both will do NVENCQSVAMD GPU recording as well as streaming . D 3 DGear will do XvidMJPEG Huffyuv for Lossless but not particularly usable , an old old codec , Action will do x 264 and it ' s own proprietary , near lossless AVI codec .
