I don't have any video advice other than you probably don't want to do anything labeled vinyasa, flow, or power because it sounds like you want stretching rather than super active flow. I did teach yoga classes, including a stretch and strengthen class, for 3x a week for 5 years in a major city and can recommend a few poses that will help. I do this short sequence after every run; it's all standing, but you do need a wall:
1.
Modified downward facing dog with hands on a wall. Face a wall and place your hands on the wall at about hip height, middle and index fingers facing up or out. Notice that the rotation in your hands is coming from your *shoulders*. Step back away from the wall so that your body can lengthen out, and take your feet hip width apart, toes pointing towards the fall. Straighten out your arms and your legs if you can (the legs can bend because the focus in this pose is on the trunk, shoulders and arms) and see if you can take your weight into your heels as you reach your palms to the wall. You will look like an upside-down L.
2.
Calf stretch on a wall. From here, I stand up and take a step forward with one foot to the wall and place my toes on the wall and heel down on the ground. Change the back foot's distance from the wall to change intensity. Not a yoga pose, but a calf stretch nonetheless.
3.
Pyramid pose on a wall. I then take that foot on the wall and place it flat on the ground, toes pointing forward. My back foot is turned out slightly or stepped out to the side to keep my hips facing forward. Hinge from the hips forward towards the wall and use the wall the same way you did in the first pose -- reaching with the arms and lengthening through the back. You can change the distance between your feet to change the intensity. The stretch is in the hamstrings, calves, possibly the glutes, and shoulders. This is not a back stretch. (

4.
High to low lunge, with side bend. Still with the same foot forward, I step the back foot back and pivot onto the back toes to come into a lunge and open up the hip flexors. Both hip points are facing forward and try to keep them lifted. Make sure your front knee does not go forward of your front ankle and that toes and knees are facing the same way. Again, change the distance between your feet to change intensity. I often slightly bend the back leg to increase the stretch. I'll take the arm on the same side as the back leg up and over, and do a side bend to get a side body stretch. (

Do 2 thru 4 on the other side.
5.
Half chair ankle to knee. Stand on your right leg and bend it slightly. Place your left ankle on your right thigh. Place your hand on a wall if balance is tricky. To increase the stretch in your glutes, either increase the bend in your standing leg or hinge more from your hips. Change legs. (

[I usually throw in a traditional
standing quad stretch here.

. Standing forward fold. Take the feet hip-width apart, toes and knees pointing forward. Hinge at the hips and fold forward. ENGAGE the hamstrings as you fold. The sensation is in the belly of the hamstring (in the event that super flexible people are reading this, the sensation is NOT in your butt.) Bend your knees if the stretch in the hamstrings is too intense. (

not the lower back. The lower back is actually super flexible, which is why it is easily injured. If you can't touch your toes, it's because the hamstrings are tight.
