I am more than content to line-up the audio to the video by using a slate. I just wanted to know if it was a good idea to buy a recorder with timecode, and if using such a device as the Sound Devices 702t would create hassles when working with non-timecoded video. Does the 702t output all audio with timecode? If so, it shouldn't affect manually syncing the video to the audio by matching the waveforms, right?

The 702T does not output ANY timecode with the audio - ever. It has a timecode connection that accepts code from external sources and/or outputs code from the recorder's internal clock during recording and playback but the TC signal is not mixed with the audio signals. Video timecode (VITC) is inserted into the vertical blanking part of the video signal, it's a part of the video data stream. But audio timecode, LTC, is linear and when present is an audio signal on its own channel completely separate from the actual audio beinmg recorded or played. Back in the analog days a half-track tape from a TC capable recorder such as Nagra would have three tracks in it - the two main left and right stereo audio tracks and a narrower track along the edge with the timecode signal. The audio file that is written to disk or flash card and is copied to your computer for editing, etc, does not contain any embedded TC information with the audio date. All it contains is just a single reference timestamp of what the recorder's TC clock was reading when the first sample was captured. Editing and audio software that understands BWF files will see that timestamp and compute the running timecode from it on the fly, those that don't just ignore it and treat the file as a plain vanilla WAV file. So there]s nothing in the audio that would interfere with using it any way you need. The only time the 702T actually outputs linear timecode with the audio is when you use the 702 as your actual playback device and take the signals from the analog audio outputs plus the (also analog) TC output and even then, everything stays isolated in its own channel.
